The invention is directed to a product life cycle management (PLM) syste m, comprising a database storing objects, preferably 3D objects, and relations between said objects. The PLM system provides a graphical user interface suitable fo r displaying to a user a graphical representation of a hierarchy of stored objects. The graphical user interface is adapted, upon selection of a displayed object by a user, to display objects related to the selected object. At a given level in the hierarchy, displayed objects are distributed according to a respective weight. The weig ht of a displayed object depends on the number of its descendants in the hierarchy, which are displayed in said graphical representation. The invention makes it possible to navigate in a database of a PLM system, storing notably complex modeled objects through interrelated data. Thanks to the principle of the weight dependence discussed above, the solution further allows the user to comprehend its progression through the organized data as well as the relations between objects and this, in an easy and intuitive way. |
